Front passenger detection sens or and passenger seat belt remind er
and warning buzzer
● If luggage is placed on the front passenger seat, the front passenger
detection sensor may cause the warning light to flash and warni ng
buzzer to sound, even if a passenger is not sitting in the seat.
● If a cushion is placed on the seat, the sensor may not detect a passen-
ger, and the warning light may not operate properly.
■
When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level.
■The tire pressure warning light may turn on due to natural causes
The tire pressure warning light may turn on due to natural caus es such
as natural air leaks or tire inflation pressure changes caused by tem-
perature. In this case, adjusting the tire inflation pressure w ill turn off the
warning light (afte r a few minutes).
■When a tire is repla ced with a spare tire
The compact spare tire is not equipped with a tire pressure war ning
valve and transmitter. If a tire goes flat, the tire pressure w arning light will
not turn off even though the flat tire has been replaced with t he spare
tire. Replace the spare tire with the repaired tire and adjust the tire infla-
tion pressure. The tire pressure warning light will go off afte r a few min-
utes.

■If the tire pressure warning system is inoperative
The tire pressure warning system will be disabled in the follow ing condi-
tions:
(When the condition becomes normal, the system will work proper ly.)
●If tires not equipped with tire pressure warning valves and transmit-
ters are used.
●If the ID code on the tire pressure warning valves and transmit ters is
not registered in the tire pressure warning computer.
●If the tire inflation pressure i s 55 psi (380 kPa, 3.87 kgf/cm2 or bar) or
higher.
The tire pressure warning system may be disabled in the following condi-
tions:
(When the condition becomes normal, the system will work proper ly.)
●If electronic devices or facilities using similar radio wave frequencies
are nearby.
●If a radio set at similar frequen cies is in use in the vehicle.
●If a window tint that affects the radio wave signals is install ed.
●If there is a lot of snow or ice on the vehicle, in particular around the
wheels or wheel housings.
●If non-genuine Toyota wheels are used. (Even if you use Toyota
wheels, the tire pressure warning system may not work properly with
some types of tires.)
●If tire chains are used.
●If a large metallic object which can interfere with signal reception is
put in the trunk.
■If the tire pressure warning light frequently comes on after bl inking
for approximately one minute
If the tire pressure warning light frequently comes on after bl inking for
approximately one minute when the “ENGINE START STOP” switch is
turned to IGNITION ON mode (vehicles with a smart key system) o r the
engine switch is turned to the “ON” position (vehicles without a smart key
system), have it checked your Toyota dealer.

WARNING
■If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so
could
cause loss of vehicle control and result in death or serious injury.
●Stop your vehicle in a safe plac e as soon as possible. Adjust the tire
inflation pressure immediately.
●If the tire pressure warning light comes on even after tire inf lation pres-
sure adjustment, it is probable that you have a flat tire. Check the tires.
If the tire is flat, change to the spare tire and have the flat tire repaired
by the nearest Toyota dealer.
●Avoid abrupt maneuvering and braking. If the vehicle tires dete riorate,
you could lose control of the steering wheel or the brakes.
■If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.

WARNING
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation p ressure
label (tire and load information label). (If your vehicle has tires of a differ-
ent size than the size indicated on the vehicle placard or tire inflation
pressure label [tire and load information label], you should de termine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS -tire pressure warning system) that
illuminates a low tire pressure telltale (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Acco rdingly,
when the low tire pressure telltale (tire pressure warning ligh t) illumi-
nates, you should stop and check your tires as soon as possible , and
inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire tread lif e, and may
affect the vehicle's han dling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper tire maintenance, and it is the driver's res ponsibility to
maintain correct tire pressure, even if under-inflation has not reached the
level to trigger illumination of the TPMS low tire pressure telltale (tire
pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warning
system) malfunction indicator to indicate when the system is no t operat-
ing properly. The TPMS (tire pressure warning system) malfuncti on indi-
cator is combined with the low tire pressure telltale (tire pre ssure
warning light). When the system detects a malfunction, the tell tale will
flash for approximately one minut e and then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle star t-ups as
long as the malfunction exists. When the malfunction indicator is illumi-
nated, the system may not be able to detect or signal low tire pressure
as intended.

If you have a flat tire
Your vehicle is equipped with a spare tire. The flat tire can be
replaced with the spare tire.
■ Before jacking up the vehicle
●Stop the vehicle in a safe place on a hard, flat surface.
● Set the parking brake.
● Shift the shift lever to P (vehicles with an automatic transmis -
sion) or R (vehicles with a manual transmission).
● Stop the engine.
● Turn on the emergency flashers. ( P. 3 8 4 )
